phacoemulsification and intraocular lens implantation in patients with congenital iris coloboma

purpose: to evaluate the outcomes and complications of phacoemulsification and posterior chamber intraocular lens implantation (pe+pciol) in patients with congenital iris coloboma. methods: in a prospective noncomparative interventional case series, 13 eyes of 9 patients (six female and three male) with congenital iris coloboma and cataract underwent pe+pciol using clear corneal incision and in-the-bag foldable hydrophilic acrylic iol implantation by one surgeon. best corrected visual acuity (bcva) and complications were evaluated six months postoperatively.  results: mean age was 46.5±5.7 years. bcva was counting finger in six eyes and between 20/200-20/100 in seven eyes, preoperatively which increased to 20/50-20/20 in 11 eyes, postoperatively (p<0.001). no serious complications occurred intraoperatively. two eyes had concomitant ocular pathology causing no improvement in their visual acuity after surgery. two patients developed postoperative monocular dioplopia. no case of retinal detachment occurred during the follow up period. conclusion: pe+pciol seems to be safe and effective in terms of visual improvement in patients with typical congenital iris coloboma and cataract.
